The Axiom i3 is a feature-rich, jacket style BC that incorporates Aqua Lung’s patented i3 inflation / deflation system. Its amazing comfort and stability come from the integrated Wrapture™ Harness System. The Axiom is made from durable, fade-resistant materials and comes in a black/navy blue/gray color combination. Integrated weights are held securely in place with SureLock II mechanical weight system and the cylinder is secured with the GripLock™ tank band. The i3 Control System, provides easy, one-touch control for inflation and deflation. Eliminates the traditional inflator that dangles at the end of a corrugated hose. i3 is simple and intuitive - just lift up on the lever to inflate and push down on the same lever to dump air. What’s more, when you push the lever down, all the dumps, upper and lower, open at the same time!
